Posey KeepSafe® Deluxe - Manual (Page 21)

Testing Alarm and Sensors
alWayS check sensor when connecting it to a Posey alarm. You can check a
sensor by attaching it to the sensor cable outlet in the alarm, activating the
alarm and placing pressure on the mattress near the sensor area and then
releasing (fig. 27). When the pressure is released, the alarm should sound.
Repeat this pressure/release test along the entire length of the sensor to
ensure entire sensor functions properly both with the bed in the flat position
and the head and/or foot articulated. If the alarm and/or sensor do not
function properly, remove the alarm and sensor from service and replace
them with a properly functioning alarm and/or sensor. Do NoT use the
alarm or sensor if it does not activate each time weight is removed from the sensor.

Steps to Apply Under Mattress Sensor
See pages 19-20 for list of warnings.
1. Select the correct sensor for your mattress.
• Lightweight sensors. For mattresses that weigh 38 – 42
lbs. (17-19 kgs.). (Cat. No. 8285L)
• Heavyweight sensors. For mattresses that weigh > 42 lbs.
(>19 kgs.). (Cat. No. 8285H)
2. Check that sensor, cord and plug are clean and undamaged.
3. Place sensor under mattress and directly on top of bed
frame. Choose one of two positions (depending on protocol
and facility policy) (fig. 25):
(A) Centered at patient’s shoulder blades; or
(B) Centered under patient’s buttocks.
4. Secure sensor to bed frame using hook and loop straps or cable ties,
depending on style of bed. Make sure sensor is flat and resting on a
solid part of the mattress.
5. Route the sensor cord to the alarm. Check that the sensor cord is not
stressed, is clear of moving parts of bed, and does not pose a tripping
hazard.
6. Insert RJ11 plug into jack labeled “sensor” on right side of alarm (fig.
26). Alarm will activate. Press the HolD button. You have 30 seconds to
transfer the patient to the bed before monitoring begins (see instructions
on page 12 for use of the HolD button).
7. Test sensor and alarm (see below).
8. Position patient in bed, with weight directly over sensor.
